01 / REVIEW

Identify both products

List manufacturer, product designation, revision and relevant substrate or finish. Similar-looking products may have different requirements. Record a supplied SKU separately from a proposed substitute.

02 / REVIEW

Name the interface condition

Explain the intended exposure and contact between materials. Ask the manufacturer or designer a bounded question about that condition. A broad statement such as suitable outdoors may not answer it.

03 / REVIEW

Keep the response scoped

Save the written response and its limitations. If the product or condition changes, reopen the request. Do not turn one answer into a blanket approval for all profiles, screws or membranes.

A junction coordination study

Concept example: a proposed fastener appears to fit a groove. The review requests the exact system requirements and actual profile data. Visual fit is retained as an observation, not entered as compatibility approval.

Use the result

Keep the completed review with the relevant project record. Assign unresolved items before relying on a conclusion. If the material, condition or document changes, revisit the affected questions.
